 When previewing a theme, my installation always shows the current theme.

 The displayed url for the preview is something like:

 http://mysite.com/?preview=1&template=classic&stylesheet=classic&TB_iframe=true&width=753&height=430

 When I change it to use 'siteurl' instead of 'home'

 http://mysite.com/wp/?preview=1&template=classic&stylesheet=classic&TB_iframe=true&width=753&height=430

 things behave properly.

 Thus, for my installation, theme previewer has unexpected behaviour when
 'siteurl' and 'home' are different.

 Patch attached, affects back to at least 2.7.   (if there is another cause
 to explore, such at .htaccess / mod_rewrite, I hope to be enlightened)
